Reusable flexible poly(vinyl alcohol)/chitosan-based polymer carbon dots composite film for acid blue 93 dye adsorption.

The design and synthesis of water-insoluble chitosan-based polymer carbon dots [P(CS-g-CA)CDs] are described. A polyvinyl alcohol/chitosan-based polymer carbon dot [PVA/P(CS-g-CA)CDs] composite film was prepared using a simple casting method to be used in dye adsorption. The composite film was characterized using FT-IR, XPS, transparency, contact angle, and mechanical properties tests, which showed the successful incorporation of P(CS-g-CA)CDs into the film and also revealed that hydrogen bonding improved the mechanical properties of the PVA film.

Phytochrome B enhances seed germination tolerance to high temperature by reducing S-nitrosylation of HFR1.

Light and ambient high temperature (HT) have opposite effects on seed germination. Light induces seed germination through activating the photoreceptor phytochrome B (phyB), resulting in the stabilization of the transcription factor HFR1, which in turn sequesters the suppressor PIF1. HT suppresses seed germination and triggers protein S-nitrosylation.

Carbon dots crosslinked chitosan/cellulose sponge capture of methyl blue by an adsorption process.

For environmental protection, organic dyes and solvents of industrial wastewater must be eliminated. Here, a citric acid-based carbon dots (CA-CDs) crosslinked chitosan/microcrystalline cellulose (CS/MCC/CA-CDs) sponge was synthesized to study its adsorption performance for methyl blue (MB) dye. The morphology of the sponge was a tangled fibre with a bundle formed by hydrogen bonds between CA-CDs and the CS/MCC composite matrix.

An Interdisciplinary Nutrition Support Team Improves Clinical and Hospitalized Outcomes of Esophageal Cancer Patients with Concurrent Chemoradiotherapy.

Background: The prevalence of malnutrition is very high in patients with cancer. The purpose of this study was to investigate whether or not a nutrition support team (NST) could benefit esophageal cancer patients undergoing chemoradiotherapy (CRT).

Methods: Between June 2012 and April 2014, 50 esophageal cancer patients undergoing concurrent CRT were randomly assigned into two groups: The NST group and the control group.

Bioavailability of organochlorine compounds in aqueous suspensions of fullerene: evaluated with medaka (Oryzias latipes) and negligible depletion solid-phase microextraction.

The wide application of engineered nanomaterials, such as fullerene (C(60)), will inevitably lead to their release into the aqueous environment, which may alter the bioavailability of organic compounds to aquatic organisms. Negligible depletion solid-phase microextraction (nd-SPME) together with medaka (Oryzias latipes) bioaccumulation were used to study the effects of aqueous suspensions of fullerene (nC(60)) on the bioavailability of eight organochlorine compounds (OCCs) (logK(OW) 3.76-6.

[Changes of T-helper 1 and T-helper 2 ratio in peripheral blood and decidua in hypertensive disorder complicating pregnancy].

Objective: To investigate the role of immune response induced by different T-helper 1 and T-helper 2 (Th1 and Th2) ratio in peripheral blood and decidua from patients with hypertensive disorder complicating pregnancy in the pathogenesis of the disease.

Methods: Peripheral blood and decidua from 12 non-pregnant women (no deciduas) (normal women group), 12 healthy pregnant women (healthy pregnant women group), 10 patients with gestational hypertension (gestational hypertension group), 25 patients with pre-eclampsia (PE) (including 10 patients with mild pre-eclampsia and 15 patients with severe pre-eclampsia) (pre-eclampsia group). Th1/Th2 ratio in peripheral blood and decidua was determined by flow-cytometrically.
